Abstract: A load shed module configured to be connected in series between a power supply and a load is disclosed. A separate load shed module is connected in series between each load and the power supply. The load shed module determines the frequency of the voltage supplied from the power supply. Based on the frequency, the load shed module determines if utility power is connected or if a generator is connected. If the generator is connected and the frequency of the voltage goes outside of a desired operating range for a preset time, the load shed module disconnects the load from the power supply. Each load shed module includes a priority setting and reconnects its corresponding load after a predetermined time corresponding to the priority setting.

Abstract: A load management apparatus for use with an electrical system being powered by an electrical generator selectively adds and sheds loads on the electrical generator to prevent overloading of the electrical generator. The load management apparatus learns the load profile for each load during a learning mode and executes one or more load shed processes to control which electrical loads are loading the electrical generator.

Abstract: A wireless annunciator for an electrical generator displays data regarding operation of the electrical generator to provide feedback to a remote observer regarding performance of the electrical generator in meeting the demands placed thereon. The wireless annunciator wirelessly receives transmissions from one or more wireless modules and displays information based on the data contained in the transmissions. The wireless modules may be associated with sensors, for example, that measure various performance parameters of the electrical generator, such as current draw, fuel level, fuel pressure, and the like. A load management controller can communicate with one or more load-side modules, either wirelessly or across wired links, to control operation of one or more loads to avoid overloading of the electrical generator.

Abstract: A foaming nozzle assembly and method of forming a foaming nozzle useable with pressure washing systems that includes a tube and a cover that cooperates with the tube. An interior surface of the tube defines a fluid path having by a first restriction, a second restriction, and an expansion chamber between the restrictions. An air path is defined between the cover and tube and fluidly connects the expansion chamber to atmosphere for introducing air to fluid associated with the fluid path. An atomizer is disposed downstream of the restrictions and expansion chamber and mixes the fluid and air to generate foam upon discharge of the mixture from the nozzle assembly.

Abstract: A nozzle assembly and method of forming an adjustable spray pattern nozzle assembly that is usable with pressure washing systems includes a first body and a second body that are positionally secured relative to one another. The first body includes a fixed shaped orifice that defines the exit of a fluid spray from the nozzle assembly. The second body is disposed upstream of the first body and includes a pressure dependent variable shape orifice. The second body is formed of a resilient material that allows flexure of the second body in response to pressure of the fluid flow. Flexure of the second body manipulates the shape of the variable shape orifice and thereby allows the nozzle assembly to provide various spray patterns without user manipulation of the nozzle assembly.

Abstract: A nozzle assembly and method of forming an adjustable spray pattern nozzle assembly includes a mount body, a nozzle body, and a collar that movably cooperates with the mount body. The mount body is constructed to cooperate with a discharge end of a wand and such that the nozzle body can be captured between the mount body and the collar. The nozzle body defines an uninterruptible fluid flow path through the nozzle assembly. The nozzle assembly includes an interruptible fluid flow path that is defined by a positional relationship between the nozzle body and the collar. The collar movably cooperates with the mount body to allow the selective combination of flows associated with the uninterruptible and interruptible flow paths to manipulate the spray pattern generated by the nozzle assembly.

Abstract: A pressure washing system that includes a pump configured to generate a pressurized fluid stream and a wand that is connectable to the pressurized discharge of the pump. The wand includes a trigger and a nozzle that are exposed to the pressurized fluid path. The wand includes a treatment fluid path that is isolated from the pump pressurized fluid path. A reservoir configured to receive a treatment agent is disposed in the treatment fluid path and is connected between the water source and an outlet proximate the nozzle. A control is connected to the wand proximate the trigger to allow selective introduction of treatment agent contained in the reservoir to be introduced into the pressurized fluid flow downstream of the nozzle.

Abstract: A load control module is provided for use with a transfer switch apparatus that controls the delivery of standby electrical power to a load during utility power interruption. The load control module selectively brings loads online to receive standby electrical power to prevent overloading of the electric generator that is providing the standby electrical power. The frequency of the electrical power is also monitored and if a low frequency condition is detected, loads are taken offline (shed). A method to flag those loads that induce an overload condition is also provided.
